SNOW-REMOVING MACHINE.

Application filed July 30, 1923. Serial No. 654,757.

To all whom it may concern:

Be it known that I, MARSOP SoUHIoIAN, a subject of the Turkish Empire,residing at Lawrence, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Snow- RemovingMachines; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in street cleaning machines andrelates more particularly to those designed for rapidly removing snow.

The object of the invention is to provide a comparatively simple machineof the class set forth which may be advantageously used upon the frontof a motor truck to scrape the snow from the streets and dump it intothe truck body to be carried to a suitable place for discharge.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description 7 beingsupplemented by the accompanying drawing:

Figure 1 is a top plan view of a machine constructed in accordance withmy invention.

Fig. 2 is a side elevation.

Fig. 3 is a side elevation partlyin vertical section.

Fig. 4: is a partial side elevation looking in the opposite directionfrom Fig. 2.

Fig. 5 is a fragmentary plan view showing the arrangement which may beemployed if the snow has packed and frozen upon the street.

In the drawings above briefly described, the numeral 1 designates thechassis frame of any desired form of motor truck, this truck beingprovided with a suitable dump body 2 and having a drivers cab 3 in frontof said body. The front end of the chassis frame 1 carries a pair ofhorizontally spaced guides 4 for a pair of upstanding arms 5 which risefrom a longitudinally disposed snow scoop 6, said arms being normallyheld in the guides 4 by set screws or the like 7. The scoop 6 isprovided with a pair of caster wheels 8 having adjusting screws 9equipped with hand wheels 10, whereby said scoop may be verticallyadjusted to any desired height when the screws 7 are loosened. In thepreferred form of constructlon, the bot- ..tom of the scoop 6 inclinesrearwardly as indicated at 11, to a point near its rear end, the rearportion of said bottom however, being downwardly off-set to provide adepression 12 into which the snow is forced and from which it iselevated by an endless elevator 13. In the front portion ofthe scoop 6,I preferably mount a rotary beater 14 which feeds the snow rearwardly insaid scoop and prevents it from piling up at said front end of thelatter. Also, in order that a wider area may be cleaned at a singleoperation if desired, I prefer to provide a pair of extension plates 15slidably contacting with the lower side of the bottom 11 and providedwith upstanding side flanges 16. These plates are pivoted at 17 to thebottom 11 and may be swung outwardly when desired. For swingingtheplates 15, I have shown bell cranks 15 fulcrumed on the sides of thescoop 6 and connected with the flanges 16 by links 18, said bell cranksbeing connected to rearwardly extending rods 19 leading to appropriatehand levers or the like 20 adjacent the drivers seat.

Mounted longitudinally upon the cab 3, is a trough 21 into which thesnow is dropped by the elevator 13 and a rotary beater 22 extends acrossthe rear end of said trough and operates in close proximity to therearwardly declined bottom 23 of said trough and thus preventsaccumulation of snow on said bottom and forces said snow to dischargeinto the dump body 2.

I prefer to drive the parts 13, 14 and 22 in the manner illustrated,from the rear axle 24 of the truck. At 25 I have indirated a drive chainfor the axle 24, although other driving means could of course beemployed. The axle 24 drives a transverse horizontal shaft 26, under thebody 2, by means of a chain 27 and suitable sprocket wheels, or otherdesired means, and another transverse shaft 28 is provided in front ofthe shaft 26, the two shafts being rotatably supported by appropriatebearing plates 29, suitably mounted on the chassis frame 1. For drivingshaft 28 from shaft 26, I have provided said shafts with spur gears 30both of which mesh with another gear 31 slidably mounted on a suitablestub shaft 32, provision being made whereby said gear 31 may be shiftedout of mesh with the gear 80 when the machine is to be thrown out ofoperation. In the construction shown, a bell crank 33 mounted on theframe 1, has pivotal connection with the hub of the gear 31 and a rod33' extends forwardly from said bell crank to a hand lever 34: withinreach of the driver.

Under the drivers seat, orat some other suitable location, I provide atransverse horizontal shaft 35 which is driven by a chain or the like 36from the shaft 28. said shaft 35 being connected with the shaft of therotary beater 14, by chains 37,. Gearin 38 at one end of the shaft 35connects thls shaft with another transverse horizontal shaft 39 which isconnected by a sprocket chain 40 with a transverse shaft 41 extendingacross the front end of the trough 21, said shaft 41 having sprockets 42which drive the endless elevator 13, the lower end of this elevatorbeing passed loosely around a roller 43 in the rear end of the scoop 6.The shaft ll is operatively connected with the shaft of the beater E22,by suitable gearing 44.

The construction so far described. will operate eifectively for cleaningcomparatively loose snow from the streets, but if the snow has becomepacked and frozen, it is desirable to use the arrangement disclosed inFig. 5. In this figure, I have shown a toothed plate bolted to andextending beyond the front end of the scoop 6 and instead of the rotarybeater 14:, I make use of a driven shaft 51 having a plurality of spacedsaws 52 with pointed pick teeth 53 between them. By employing thisassociation of parts, the hard frozen snow, sleet or the like, may beeffectively scraped from the street, broken up and then carried upwardlyby the elevator 13. This elevator discharges into the trough 21 and thebeater 22 forces the snow or the like rearwardly and distributes it intothe body 2.

Whenever the machine is loaded the lever 34: may be operated to throwthe gear 31 out of mesh with the gears 30, thus permitting the entiremachine to be driven to a suitable dumping point.

As excellent results may be obtained from the details disclosed, thesedetails may if desired be followed, but within'the scope of theinvention as claimed, numerous minor changes may be made.

I claim 1. The combination with a motor truck having a drivers cab and adump body in rear of said cab andextending to the rear end of the truck;of a trough-shaped snow scoo in front of and connected to said true alongitudinal trough. supported horizontally on top of said cab andextending from front to back thereof to discharge into the truck body,an. elevator in front of the cab from the rear end of the scoop bottomto the frontend of the trough, a rotary beater in the front end of thescoop above the bottom of said scoop and spaced rearwardl from the frontend of said bottom for forcibly throwing the snow rearwardly to theelevator, and a rotary beater in the rear end of said trough forthrowing the snow directly rearward into the truck body.

2. The combination with a motor truck; of a pair of transversely spacedvertically disposed guides carried by the front end of said truck, asnow scoop in front of the truck having rigid upstanding arms slidablyreceived in said guides for vertical adjustment, vertically adjustablecaster wheels for assisting in vsupporting said scoop, and means forsecuring said arms to said guides in any position to which they may beslid.

U
